French voters are being deluged with false stories on social media ahead of the country’s presidential election, though the onslaught of “junk news” is not as severe as that during last year’s U.S. presidential campaign, according to a study by Oxford University researchers.The study to be published Friday and another published on Wednesday add evidence to complaints by officials in France, Germany and the United States that Russia is trying to replicate its cyber-powered election meddling in American politics.Just days before France votes in the first round of a presidential election, the study said misinformation at times has accounted for one-quarter of the political links shared on Twitter in France. It defined “junk news” as deliberately false stories and those expressing “ideologically extreme, hyper-partisan or conspiratorial” views with logical flaws and opinions passed along as facts.
